Welcome to the Marine Modeling and Analysis Branch Operational
Technical Procedures Bulletin Index. Each Technical Procedures bulletin (TPB)
describes an operational Guidance Product which this Branch produces.
From time to time as guidance products are modified or refined, these tpbs
are modified. The modification date will alert readers to the fact that changes
have been made to the tpb. If a product is replaced by new technology then a
new tpb is written and the old tpb is transferred to the obsolete tpb Index.

from time to time and will be repaired as rapidly as possible, during normal
